DISCHARGE MECHANISM FOR BITUMINOUS IDIS'IRTBUTORS.

Application filed May 7,

i To all whom it may concern:

Be it known that LAN'rI-IONY FRIOKER, a citizen of the Uiiited States,residing at Lakewood, in the county of Cuyalioga and State of Ohio, haveinvented certain new and useful Improvements in Discharge .Mechanism forBituminous Distributors, of

which the following is a specification.

This invention relates to discharge mechanism for bituminousdistributors.

hen distributing bituminous material or petroleum products over aroadway it has been customary to circulate the heated bituminousmaterial through a manifold and discharge the same from said manifoldunder pressure through a series of ports or openings spaced along themanifold, each of which projects its own jet of material downwardly.Such an arrangement has been found necessary in order to provide thenecessary controlling valve mechanism to regulate the flow withoutpermitting the bituminous material to congeal or harden when the portsare closed or the flow stopped. In order'to thoroughly cover the roadwaywith a. uniform coating the ports or outlet openings from the manifoldshould be as close together as possible so as to insure over. lapping ofthe jets one upon another. How ever, the necessity of providingoperating mechanism for the valves has necessitated placing the valves"farther apart than is desirable.

One object of the present invention is therefore to provide valvemechanism for controlling the flow from the manifold which permits theports or outlet openings to be placed very close together and at thesametime enables the valve devices to be easily manipulated, butnevertheless in a positive manner;

A further object of the inventionis to provide improved valve mechanismfor a dis tributing manifold including a plurality of sets or gangs ofoutlet ports or openings differing in size from each other, each of saidgangs of openings being controlled by its own set of valve devices,thereby enabling the separate gangs to be independently operated forvarying the "quantity of material deposited without special adjustmentof the pressure of the liquid or of the valve devices or dischargenozzles.

A further object of the invention is to enable varying quantitiesofmaterial to be deposited upon the roadway but neverthe- 1919. semi No.295,319.

less to be distributed uniformly over its entire surface.

A further object of the invention is to provide an improved form ofvalve device for controlling the flow of material from the distributingmanifold, said valve device being of such form and being so located onthe distributor as to be in heat conducting relation to the heatedliquid material circulated theret-hrough, whereby the valve body andported parts are maintained hot so as to pre vent chilling or congealingof the material or clogging of the valves when closed.

A further object of the invention is to provide a distributor forbituminous or similar heated liqui-d'inaterials whose bottom wall ispierced at intervals to form hollow ported valve bodies integral withthe distributor,

whereby the valve bodies and the cooperating plugs therein are heated bythe liquid material to prevent clogging of the ports.

Further objects of the invention aref'in part obvious and in part willappear more in detail hereinafter.

and arrangement of parts hereinafter described and claimed.

In the drawings which represent one suitable embodiment of theinvention, Fi 1 is a rear elevation; Fig. 2 is across section on theline 25-2, Fig. 1; Fig.3 is a similar section on the line 3-3,- Fig. 1;Fig. 4 is'a The invention comprises the construction The dischargemechanism shown in the drawings comprises a manifold 1, which is in theform of a hollow tubular member whose inner chamber 2 is connected bythe supply pipes 8 and return pipe 4 to a reservoir (not shown) fromwhich the liquid bituminous material is circulated under pres sure bygravity or a pump through the manifold, as is usual.

Along its bottom the manifold-is provided at intervals with dischargenozzles through.

which the material isdischarged in the form of jets upon the roadway.These nozzles are in two gangs, marked respectively 5 and 6 the membersof the two gangs alternating in order along the manifold. Each of saidnozzles is a simple tl'ireadedmember screwed into an opening in. thebottom of the manifold and provided with a through-opening terminatingat its bottom in an outlet or discharge port 7. The discharge ports of'willsuflice for all of that gang, and the valve members in each gangare simultaneously controlled. Howeventhe valve devices for the twogangs may differ from each other and each set of valve devices iscontrolled independently of the other. 7

Fig. 2 represents in detail oneof the valve devices for controlling thegang of outlet openings through the nozzles 5. As illustrated eachnozzle 5 has abore to receive a valve stem 8 seating downwardly againsta shoulder at the bottom of said bore and normally held to its seat by acompression spring 9. Valve rod 8 slides through a bushing 10 threadedinto the upper portion of the manifold, and the joint around said stemis sealed by a packing 11 in a gland nut 12. Each of the valve stems 8has a loose pivotal connection at its upper end with one arm of a bellcrank lever 13. The other arms of said bell crank levers are pivotallyconnected to a common operating rod 14. By movingsaid rod to the rightin Fig. 1 all of the valve stems 8 are elevated to open the outlets fromthe nozzles 5 and produce discharge from all of said nozzles. Since saidnozzles are located at uniform 1nv tervals along the full length of themanifold a-uniform coating of bituminous material is discharged over theroadway.

Fig. 3 illustrates the valvemechanism' for controlling the outletsthrough the other 7 gang of nozzles 6. Each of said nozzles has athreaded member screwed into the bottom of the manifold with its openingaligned with an opening 15 through the bottom manifold wall. At eachnozzlethe bottom manifold wall is thickened to form a valve body portion16 having a tapered bore to receive a tapered plug 17 having a throughport 18 therein, said plug being held in place by a nut 19 threaded uponits reduced end.

.The opposite squared end of each plug has connected thereto a lever arm20, allof said lever arms being pivotally connected at their outer endsto a common operating member In the pos1t1on of the parts shown in'Figs. 1 and 3 all of the tapered valves are closed, but if the rod 21 ismoved to the left in Fig. 1 all of said valves are simultaneouslyopened, and as said valves are distributed at uniform intervals alongthe entire length of the manfold uniform distribution of bituminousmaterial occurs over the entire roadway.

Since the discharge openings of the two sets of nozzles are of differentsize one gang of openings can be used for a light coat of material andthe other set of openings for a heavier coat of material, while a stillheavier coat can be applied by opening both sets of outlets at the sametime. Nevertheless it is unnecessary to vary the pressure of the supply,or to more or less choke or restrict the flow by a valve located in thesupply conduit, nor is any adjustment of individual valve devicesnecessary.

The use of two different types of valve devices enables each set to becorrectlyoperated independently of the other without interferencebetween the operating devices for the two gangs. For example, theoperating levers and rod for the valves shown in Fig 2 are at the top ofthe manifold, while the operating devices for the other gang of thevalves are at one side of the manifold.

Moreover the first set of valVe'referred to are vertically slidingmembers, whereas the second set are horizontally disposed plugs. Whenthe gland nuts 12 are considered the two sets of valves can therefore belocated closer together than if all the valves were of the same type.

The valve arrangement shown in Fig. 3

also prevents any possible chilling or con-,

gealing of the material circulatedthrough the distributor because thevalve body and the ported plug are in close heat conducting relation tothe material in the distributor.

Consequently they are kept hot sothat even if the valves are closed thematerial does not congeal in theports. Also, by making the valve body anintegral pa'rtxofthe bottom wall of the distributor, with the valve plugtherein, not only are the valve parts kept hotbut the construction issimple and can be made at lower costthan prior constructions for thesame purpose.
